I use NetKVM (VirtIO network) driver from there all the time, because
e1000 is bad.

However, I've read a number of bhyve resources including
https://wiki.freebsd.org/bhyve/Windows and I've never found a success
story with paravirtualized Windows disk drivers.=20

If anyone has been successful with viostor(?), please share your experience.

I would be especially grateful for instruction how to install Windows on
a viostor disk instead of ahci-hd.
